Improved technologies to reduce methyl bromide emission
Improved technologies have been used in Israel in order to reduce methyl bromide emission. Trials have been carried out in potato fields infected with Verticillium dahliae. The use of virtually impermeable films (two outer layers of low density polyethylene with a nylon or an ethylene vinylalcohol layer in the middle) during the exposure period can allow a 50 % reduction of dosage (25 g/mý instead of 50g/mý) and a reduction of methyl bromide emission with the same efficacy.
